CALENDER OR THE LIKE.

Application filed October 25, 1920. Serial 1T0. 419,217.

To all whom z't may concern:

Be it known that I, DAVID R. BOWEN, a citizen of the United States, residing in the town of Ansonia, county of New Haven, and State of Connecticut, have invented certain new and useful Improvements in Calenders or the like, of which the following is a full, true, and exact description.

This invention, relates to calenders and particularly to the supporting structure for the rolls.

In the types of calenderin machines now in general use, a series of ro ls are mounted in superposed relation in vertical standards or housings to form what is ordinarily stack. These vertical housings and other parts of the ca enders, which, being largh and heavy machines necessarily should ave strong and rigid supporting members of relatively large base area. It is particularly im rtant that these machines should be rigi ly supported when used in connection with the fine gauging of soft rubber and the like. M improvements are designed to increase t e rigidity of the supporting structure.

It is also common in the calender machines now in use for the ends of rolls or roll' necks .and the gears secured thereon to project beyond the standards or-housings where they are in an exposed position and the clothing of the operator is apt to come into contact with the roll necks or to get caught in the gears. My improvements are also designed 'to overcome this defect, present in the machines heretofore used.

One object of this invention is to provide a calender of generally improved construction and operation.

Another object of this invention is to materially increase the rigidity of the vertical standards or housings in machines of this character. Y e

A. further object of the invention is to provide thevertical standards with means to enclose the roll ends and gears thereon, so that they will not be in an exposed position in operation.

To these and other ends the invention resides in thenovel features and combinations of parts to be hereinafter described and.

claimed. v

In the accom anym drawm Fig. 1 is :a ront eevatlona view of a ards 12 and the have chosen to illustrate in the drawings accompanying this application comprises a stack of calender rolls 11, supported in two vertical standards 12, which are spanned at the top by a supporting table 13. These rolls may be supported in the standards 12 in any suitable manner. As shown in the drawings, each of the standards 12, consists of two substantially parallel spaced members 12 which are joined at their lower ends by the base web 12", thus providing longitudinal openings 14 in which are suitably secured journal boxes 15 which rotatably receive the spindles or roll necks 16 of the rolls 11.

I have illustrated my invention as applied to a calender having an overhead motor driveof a type known prior to' my invention and to which I make no claim. The drive mechanism for; the rolls is supported upon the upper ends of the standards 12 and the table 13. This drive mechanism consists .of-

cured to one end of the middle roll spindle 16. The pinion 19 and the gear 20 are suitably enclosed in a housing 21..

It will be seen by reference to the drawings that the roll necks or spindles 16 project beyond the body portions of the standgears 22 which are secured to the left ends of the spindles 16 are not protected by suchbody portions. Moreover, it will also be apparent that the supioo porting table'13 and the upper ends of the standard 12 will be required to support a Wei ht of great magnitude in the structure of t e calender rolls themselves and of the driving mechanism which is, in the embodiment shown, located on the to of the machine frame. It' is, therefore, important to provide standards of great rigidity which lid will be able to bear the required weight, and which will be able to provide a rigid support for the device notwithstanding the vibrations of the machine when in operation. This will be found particularly desirable when the machine is used on the fine gangin of soft rubber.

he vertical standards 12 are, therefore, provided with flanges 23, one of which extends laterally from the panels on each side of the longitudinal openings 14. As shown, in Figs. 3, dand 5, these flanges extend ver tically throughout the entire length of the standards 12 and the upper portions thereof assist in supporting the broadened upper surfaces 242 which connect the up er ends of members 12 and cooperate wit the sup porting table 13 in roviding a base for the drive mechanism. -t will be apparent that these flanges not only give rigidity to the standards 12 but by their continuation to the upper ends of these standards they serve as a firm underpinning for the supporting surfaces 24:.

The upper bases at are provided at their inner faces with shoulders 24 which cooperate with com lemental shoulders l3 formed on the end surfaces of the table 13. This provides a rigid support for the table and at the same time furnishes a flat supporting base for the driving mechanism as the upper surfaces of the member 2a and table 13 are in the same plane. Bolts 27 are then passed through allgning openings in.

the standards and table to secure the parts firmly together.

As shown in Figs. 1, 3 and 5 of the drawing, thesefianges extend laterally from the standards 12, and in the general longitudinal direction of the rolls 11 to a sufioient distance to form housings for the rollnecks or spindles 16, which, as has. been stated, project beyond the body portion of the standards 12. lhe gears 22 which are provided on one of the ends of the rolls 11 will also lie within the space between these flanges, which therefore serve as a housing for these gears. The spindle ends onthe right side of the machine, as shown in Fig. 1, will pro ject into the space between the flanges, so that the flanges will serve as a housing to protect the otherwise exposed ends of the spindles. The flange portions may, as shown, be cast in one piece with the standards 12, or if desired, they may be separately rovided and secured-to the standards by lting or other suitable means. The flanges 23, as well as the standards 12, will .be' rovided with base portions 25 through w ich suitable pins or bolts 26 may be inserted to secure the machine in position upon a suitable base. The continuation of the flanges to the lower ends of the standard and the provision of the broadened base portions on the warwill w increase the base area tion of the machine in so far as the protected parts, in the normal operation of the machine, are not likely to catch the persons or the clothing of the attendants, as has beenv the case hitherto in machines with exposed roll ends; and again these flanges have an important function in supporting from beneath a drive mechanism of greater base length than the distance between the outer' faces of the body portions of the standards or end frames.

It Will be apparent that it is particularly advantageous to use my improved construction or" the supporting standards and the frame of the machine in combination with an overhead drive of the type shown. The electric motor and other parts of the drive mechanism supported u on the upper ends of the standards and i318 table 13 are of great weight and will require a strongand rigid standard construction. The center of gravity of the whole device is raised by the positioning of the driving members upon the top of the roll stack so that a broader base area is needed to provide a stable support as well as a stronger direct supporting means to carry the weight of the motor and associated driving elements, Moreover, the vibrations of the motor when in operation will be transmitted to the frame and to overcome this efiect it is also particularly desirable to use my novel standard construction Mill wherein the vibrations of the calender are 7 reduced to a minimum. It will be understood, however, from what has been said above that I make no claim to the overhead drive per se, but only in combination with the improved frame construction of my invention 1 While l have illustrated in the drawings and described a preferred embodiment of my invention, it will be understood that I do not intend to be limited in all of its details to the exact form shown and described, for the invention is capable of many modifications and of various changes which will lie within the scope of the appended claims.
